Springs and Work

2 Joules of work is needed to stretch a spring from its natural length of 30cm to a length of 42 centimeters. How much work is needed to stretch it from 35cm to 40cm?

Sorry, I know this is simple but I'm messing up somewhere because I'm not getting the correct answer of 25/24 or approx. 1.04 Joules

Any help is appreciated. Thanks.
